Depending on the ports available on your laptop, you may or may not need an adapter. Most projectors include an HDMI input port, so if your laptop has a full-size HDMI port, you probably won't need an adapter. The same is true if your projector has a VGA input and your computer has a VGA port. In most other cases you will need an adapter.
Here's a description of the types of ports your laptop may have and the adapter you'll need to get, if any:
HDMI port: If your laptop has a full-size HDMI port and your projector has the same type of port, you don't need an adapter. HDMI is the easiest way to connect a projector to a laptop.
Mini HDMI Ports: Also known as HDMI type-c, they are functionally the same as HDMI, just smaller. You can use a cable or adapter with HDMI on one end and HDMI type-c on the other.
DisplayPort: These are more common on desktop video cards, but your laptop probably has one. If so, then you can use an HDMI to DisplayPort cable or HDMI to DisplayPort adapter.
USB-C: If your laptop uses USB-C to output video, you'll usually need to purchase a docking station that includes an HDMI port or a USB-C to HDMI adapter. However, some projectors do support USB-C video input, in which case you can connect your laptop directly to the projector via a USB-C cable.
VGA: This is an older video connector limited to 640x480 resolution. If your laptop and projector both have VGA ports, you can connect them with a VGA cable without the need for an adapter. However, you'll also need to use another method to send the sound from the laptop to the projector, as VGA doesn't carry audio signals like HDMI.
